About GC BJJ Academy
Our story, our mission, and the instructor behind it all.
Our Mission
More Than a Gym
GC BJJ Academy was founded with a simple belief: martial arts training should be accessible, authentic, and transformative for everyone - regardless of age, background, or experience level.
We're building a community where people come to train hard, support each other, and grow - on and off the mat. From our Little Champions program for 3-year-olds to our adult competition team, every student at GC BJJ Academy receives world-class instruction in a safe, ego-free environment.
Located in Woburn, Massachusetts, we serve families and individuals from Burlington, Winchester, Stoneham, Reading, and surrounding communities.
Head Instructor
Professor Gabriel Costa
BJJ Black Belt · 15+ Years Experience
Professor Gabriel Costa began his Brazilian Jiu-Jitsu journey over 15 years ago and has dedicated his life to the art. As a Black Belt competitor and instructor, he brings a depth of knowledge and passion for teaching that is felt in every class.
His teaching philosophy centers on three principles:
Strong Fundamentals
Every technique is built on a rock-solid foundation. Beginners and advanced students alike benefit from Professor Costa's emphasis on getting the basics right.
Individual Development
No two students are the same. Training is adapted to each person's goals, body type, and pace of learning - whether that's self-defense, competition, or fitness.
Welcoming Environment
The best academy is one where everyone feels they belong. From day one, new students are welcomed, supported, and encouraged by the entire team.
